AN inmate at a privately-run jail was given the freedom of the prison after two officers forgot to lock him in his cell.

Guards only noticed the rogue prisoner at Addiewell Prison in West Lothian after he was spotted on CCTV wandering the jail’s halls and corridors.

Two prison officers responsible for locking up inmates in the jail’s Forth B hall have been suspended while bosses investigate the blunder.

A source at the jail said: “They accidentally left his cell open over a secure lock-up period last week.

“They are meant to go round each cell, check everyone is in, lock and bolt the doors, then go round again double-checking the locks. He got spotted wandering around on CCTV so screws came and locked him up.”

A spokeswoman for Sodexo Justice Services, who operate the jail, said: “We can confirm that two prison officers are currently suspended pending an investigation.”

The jail has been dubbed the Addison, after the Radisson hotel chain, because cons enjoy flat-screen TVs, Sky Sports and en-suite bathrooms in their cells.
